AUToMATIc rRE'ssURE- LL RELEASE FOR CLOTHESWRINGERSf leases for Clothes-WVringers, of which the following is a specification, reference being had therein to the accompanying drawing. This invention relates to certain new and useful improvements in clothes wringers having means for releasing the pressure through the medium of a breakable top bar, the, object of this invention being to provide novel means for holding the sections of the breakable bar in position when forced together in order to enable the sections to be placed in position within the wringer frame by forcing downwardly thereon so as to reset the release.

Another object of my invention is to provide a locking member which is normally held in such position that when the sections of the top bar are forced together, the

hooks willibe drawn into engagement with the beveled faced keepers so as to allow said hooks to ride over said keepers to lock the sections together in such a manner that they will. be held in horizontal alinement to enable the pressure screws to be adjusted, said locking means being so constructed that the hooks can be readily swung to one side of the keepers to release the sections in order to allow the sections to move upwardly.

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.

In the drawings, Y I Figure 1 is a side elevation of a wringer partly in section showing the application of my improved construction of release thereto, the breakable bar being shown raised in dotted lines;

. Fig. 2 is a detail horizontal section partly in elevation of the top bars of my improved construction of locking member therefor;

frame, the upper bearings being provided with -spring supports 5 carrying pressure springs 6 engaged by bearing plates 7 carried by a pressure bar 8.

Secured to the upper ends of the side bars i are capmembers 9 under which are adapted to be arranged the free ends of a sectional top bar formed of sections 10 and '11 pivotally connected together. by a hinge 12 at their lower edges and between which is arranged a pivoted locking member which is preferably mounted on a screw 14 secured in the end of the section 10, said locking member having lugs 15 to each side of its pivot for limiting the swinging movement thereof. The locking member 13 is preferably formed of a platehaving but-v tons 16 secured on its upper edge at each end .adapted to be struck by the operator so as to rock the locking member 13 on its pivot 1'4, the movement being limited by the stop lugs 15 coming into engagement with the hinge 12; I I

Secured on the top of the sections 10 and 11 of the breakable top bar are keepers 17 and 18 which are provided with beveled faces adapted to cooperate with the beveled faces of depen ding hooks 19 and 20 carried' by the locking member so that when the sections of the top bar are forced downwardly so as to bring the sections into hori- -zontal 'alinement with one another, the

beveled faces of the hooks l9 and 20 will be brought into engagement with the beveled.

faces of the keepers which enables the locking hooks to ride over the keepers into the position as shown in Fig. 2 so as to securely lock the sections together.

Secured on the top of the section 11 under the keeper 18 is a flat spring 21 having arms 22 extending over. the upper edge "of the locking member 13 in such a manner that the locking member will be normally held in the position shown in Fig. 3, so as to hold frame carrying pressure screws the hook members in engagement with the keepers. v

The free ends of the sections 10 and 11 are rounded as shown in Fig. 2 which allows the sections to move from under the cap members 9 when they are released by the locking member so that they can ride upwardly into position as shown in dotted lines in Fig. -1.

The free ends of the sections of the breakable bar carrying pressure screws 10 and 11 mounted in boxes embedded therein which are adapted to engage the bearing plates 7 so as to adjust the pressure on the pressure rolls.

In the operation'of arelease as herein shown, assuming that the breakable bar formed of the sections has been placed in positionx within the wringer frame as shown in full lines in Fig. 1, with the locking members in position over the keepers, when it is desired to instantaneously release the pressure on the pressure means in case of a foreign object being drawn between the pressure rolls, the operator strikes one of the buttons 16 which swings the locking member off of the keepers and allows the sectional top bar to break and move upwardly as shown in dotted lines in Fig. 1, which moves the pressure screw carried thereby in the position shown so as to release the pressure on the pressure rolls.

When the sections assume the position as shown in dotted lines in Fig. 1, after being released, the locking member returns to its original position so that when the sections are forced downwardly, the keeper carried by the section will be brought into engagement with the beveled faces of a locking hook so as to move said locking hoolr out of the path of travel thereof to enable said locking member to ride over said keeper and engage the same.

I claim:

1. A clothes wringer, comprising a frame having pressure rolls and pressure means for said rolls mounted therein, a transversely breakable bar mounted in said for adjusting said pressure means; keepers carried by the. ends of said sectional bar, and a transverse movable spring-held locking member carried by one of the sections of said bar engaging said keepers for automatically locking said sections in horizontal aline ment.

2. A clothes wringer, having a pressure Y release comprising a sectional top bar carrying pressure screws, means for pivotally connecting said sections together, keepers provided with beveled faces carried by the abutting ends of said sections, and a transverse movable spring-held locking member carried by the end done of said sections having locking hooks with beveled faces engaging saidkeepers for automatically looking said sections ill-horizontal alinement.

3. A clothes wringer, comprising a frame having pressure rolls and pressure means for said rolls mounted therein, cap members carried by the side bars of said frame, a sectional bar having its ends disposed under said cap members, said bar having its inner ends pivotally connected together, a transversely movable locking member pivotally carried by one of said sections, means for limiting the movement of said locking member, keepers carried by the inner ends of said sections having beveled faces, avspring for holding said locking members in locked position, said locking member having spaced hooks provided with beveled faces adapted to engage the beveled faces of said keepers for automatically locking said sections together when moved into alinemei'it.

4. A clothes wringer, comprising a frame-- having pressure rolls and pressure means for said rolls mounted therein, cap members carried by the side bars of said frame, a sectio'naltop bar mounted under said cap members having rounded free ends, pressure screws carried by said top bar for adjusting said pressure means, a hinge pivotally connecting the inner ends of the sections of said top bar, a locking member pivotally m0unted on the inner end of one of said sections having buttons for rocking the same, keepers carried by said sections having beveled faces, hooks provided with beveled faces carried by said locking member engaging said keepers, and a spring for normally holding said locking member in locked position.

5. A clothes wringer, comprising a frame having pressure rolls and pressure means for said rolls mounted therein, a top bar mounted in said frame having means for adjusting said pressure means, said top bar being formed of sections pivotally connected together, a transversely movable locking member pivotally mounted on the inner end of one of said sections having spaced locking carried by the side bars of said frame, a
